Small Ramon spout flow diagram
At .75 GPM and 1 GPM the flow out of the spout is relatively well behaved. The water stream is not quite a rain chain ( as with most other well behaved flows) as the water adhering to the bottom lip thickens the water stream as it leaves the edge.
At 2 GPM the stream becomes a bit messy. Small drops of water drip off the bottom edge of the spout and drip down and forward a bit. The amount of drip and the direction may be influenced by the spout finish. There may not be a way to consistently control this
The spout can handle a considerable volume of water. Moving more that 4 GPM should not be a problem.
Spout was plumbed with ¾ in pipe using the supplied bushing. Please be careful when using smaller pipe sizes as the this will change profile.
